You my friend is facing a tough situation. I am sure there must
be arguments where either one side refuse to give in to the
other.
Your gf by giving you the Cold treatment, can be interpreted as
either trying to test how much you need her; Remember this, when a
gal feels the demand, she can raise the price. If this is the
situation, it depends on how much you can suck to it, how creative
you are to turn the situation around to make her happy. By
repeatedly calling her, smsing to her is a Mistake, you are clearly
showing your weakness that you need her more. Its a gals instinct,
remember if you lose the control, you would be having lots of
problem in future.
Or...you have totally pissed her off and she wants a way out.
But the good thing is..by being confused on whether to break up,
she probably have not found another guy yet. If she did, it would
be a strait forward Goodbye to you.
By the way, I was just watching a Chinese movie on the movie
channel about 3 playboys.. one of the dude mention.. why waste the
whole forest over a single tree, right? 
Tell us more of the situation.. perhaps a solution would be
found.
Good luck dude!
